WALL STRUCTURE.

Application filed Becember 11, 1920. Serial No. 429,921.

To all whom t 'may concer/11..'

Be it known that I, CHARLES L. MICHOD, a citizenof the United States, residing at Chicago, in the county of Cook and 'State of Illinois, have invented a new and useful Improvement in Wall Structures, of which the following is a specification..

My invention, generally stated, relates to the art of constructing wall structures, either formingthe parts of buildings, or otherwise. Y

As to one phase of my invention, it consists in improvements in the constructing of walls made of slabs of concrete or other relatively heavy material, and as to another phase of the invention it relates generally to wall structures formed of bodies which are arranged in edge-to-edge relation to form the wall.

One of my objects is to reduce the cost of constructing wall structures, more vparticularly when formed of slabs, as for example concrete; to provide for the proper sealing of the joints between the slabs; to permit of the use of a lighter framework, especially in the case of buildings, to which the slabs are secured, and still present the desired rigidity of structure; to generally im rove upon` structures of the character re erred to; and other objects as will be manifest from the following description. Referring to the accompanying drawings: Figure 1 is a face view of a wall structure, which may be a wall of a building, constructed in accordance with my invention, a portion of one of the slabs being broken awa at two different places. Figure 2 is a roken, enlarged, section taken at the line 2 2 on Fig. 1 and viewed in thedirection of the arrow. Figure 3 is a section taken at the line 3 3 on Fig. 1 and viewed in the direction of the arrow. Figure 4 is a view like Fig. 1 and of the structure' therein shown, with'the slabs removed. Figure 5 is the same as Fig. 3 except that it 1s enlarged and shows a portion only of the structure re resented in ig. 3; and Fig. 6, a broken, en arged, section taken at the line 6 6 on Fig. 1 and viewed in the direction of the arrows.

1n the particular construction shown, and in connection with which 1 have chosen to illustrate my invention, the wall is formed of a framework preferably of metal and slabs, or panels o concrete, or any other suitable material, arranged in edge-toedge relation and tied to the framework. The framework shown is formed of uprights 7 located at the ends of the wall, intermediate uprights 8 spaced 'apart from each other and from the uprights 7 preferably equidistantly, three of these intermediate uprights being shown, though it will be understood that the invention is not limited to this particular number of uprights, and cross-pieces 9 extending lengthwise of the wall structure and shown as arranged in three tiers. All of these frame members are preferably formed of metal bars, the uprights 7 being shown as Fbeams, the intermediate uprights being shown as formed each of twoangle irons 10 rigidly connected together at their rearwardly-extending ianges, and having their other flanges eX- tending in opposite directions in line with the wall, and the cross-members 9 being of angle shape in cross-section, these crossmembers fitting in between the uprights 8 and between the latter and the uprights 7, the cross-members 9 being secured in osition, as by plates 10a suitably secure as, for example, by rivets to the rear faces of the laterally-extending flanges of the intermediate uprights 8 and the uprights 7, and to the depending flan es 11 of the cross-bars 9, each of the latter eing provided with a series of holes 12 in the depending flan es 11 thereof, these holes being preferaly equidistantly spaced.

The framework described co-operates with a foundation of any desirable kind, such as that represented at 13 and which may be formed of concrete, and preferably, especially in the case of buildings, is at least partially imbedded in the ground. The uprights 7 are anchored to the foundation 13 in any desirable manner, as for example by bolting them thereto at the feet 14 provided on the lower ends of the uprights 7, the intermediate uprights 8 being shown as resting on the upper surface of the foundation.

The anels are represented at 15 and are prefera ly of the reenforced, pre-cast, type. As shown, these slabs are relatively high, as compared with their width, and the reen# forcementtherein is formed of a series of wires 16 extendin substantially parallel with each other and in spaced relation, the long way of the slab, with wires, representI lill@ ed at 17 and preferably extending parallel with each other and at a right angle to the wires 16, extending crosswise of the slab, the wires 16 and 17 being preferably tied together at their intersections, by wires as represented at 18. Cast inthe slab are plates 19 which extend crosswise thereof and are spaced apart vertically to correspond with the vertical spacing of the cross-members 9, these plates containing apertures 20 through which bolts 21 also cast in the slab, extend, the threaded ends of these bolts extending beyond the rear face of the slab. The bolts 21 are spaced apart to cora .respond with the spacing of the openings work referred to being in position, the slabs 15 are set up on end on the foundation I3 to the position shown wherein they extend in edge-to-edge relation, and are then fastened in place to the framework as stated. The arrangement of the parts of the structure is such, as shown, that the force exerted downwardly by the slabs, is taken by the foundation 13 by reason of the support of the slabs at their lower ends on the foundation, the framework referred to being provided primarily for the purpose of maintaining the slabs in upright position.

Provision is made for rendering the wall structure continuous from end to end by tying adjacent slabs together. This may be accomplished in any desirable manner, but

. preferably in the way shown which involves the formation of the upright edges of the slabs, exce t the outermost edge of each of the end sla s, with a substantially V-shaped channel represented at 23, the wires 17 being of such length that they extend into the respective 2channels to a position in which,

when the slabs are assembled with each other as stated, they overlap adjacent the ends of these wires, as represented more particularly in Fig. 6. After the slabs have been positioned as stated, any suitable cementitious material, as for example cement, is run into the spaces provided by .the opposing channels 23, thereby imbedding therein the 'ends of the wires 17, the material referred to binding the slabs together and sealing the joints therebetween. j

It will be understood from the foregoing that by constructing a wall structure in accordance with my invention the same may be made continuous and of practically uniform strength.V

The supporting of the slabs directly on be constructed presenting the desired resistance to deflection, but with a lighter frame than hitherto provided, whereby the production of the structure is rendered much more economical. Furthermore, the arrangement shown acts to very eectually stiifen the framework, which is of advantage where, as oftentimes in the case of buildings, the framework is required to support objects or structures other than the wall itself.

It will be understood that in the case of buildings where the wall isto be of greater height than the longest dimension of the slabs, the superposed tier or tiers of slabsv would be supported at their lower ends on a relativelysolid support, as for example bars extending from' one end upright to the other and connected therewith, as distinguished from hanging slabs on the framework, which would thus require the framework to be suffciently heavy to support the slabs.

While I have illustrated and described a particular construction embodying my invention, I do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered, and the invention take other forms, within my invention. A

What I claim as new, and desire to secure by Letters Patent, is:
